This article deals with the issue of viewers’ perception, observation and understanding of certain works of art that can reasonably be linked to the creation of textiles. In this study, we wanted to justify the assumption that the visual structure of a pattern may be comparable to the grammar of some paintings and graphic works. Our viewpoints are based on the postulate that a work of art can be transformed and consequently perceived as a pattern through repeated variations and that the visual expressiveness of a pattern can also achieve the status of a work of art. With the analysis of image areas, we tried to prove that the structure of the visual field is one of the essential factors that affect both the perception of paintings and art matter patterns. The image surface is the fundamental part of the area perceived in the visual system. Every image surface in space can be observed in a visual and artistic way. When an image surface is a part of a work of art, e.g. a pattern or picture, we experience and analyse it from the perspective of art viewing. In artistic terms, the image surface can be perceived as an art surface of paintings, drawings, patterns etc. The aspects of its creation are reflected in the properties of textures, structures, factures, patinas and raster. The features of colour relationships and colour modulation which can be seen in the form of textures and raster are implied by fine art in different models. The halftoning and texturing can connect the patterns of Lia Cook and Ghada Amer textile images, as well as of Victor Vasarely and Bridget Riley paintings. In Riley’s paintings, the textural grammar is highlighted in the shape structures forming the visual field, whereas Ghada Amer also expresses herself through the hapticity of textile materials which are mainly used in the conceptual sense.

Colour management is the basic method which guarantees the optimal appearance of colour on computer displays in digital prepress. The aim of this research was to determine whether it is possible to predict the appearance of colour on a wide gamut display using chromatic adaptation transforms when changing the display white point from 6500 K to the following values of the colour temperature of the display white point: 5000 K, 5500 K, 7000 K, 7500 K and 9300 K. For a colour adaptation, three chromatic adaptation transforms were used, i.e. bradford, von Kries and XYZ Scaling model. The measurements obtained at 6500 K white point were used as reference to calculate the adapted colour values for the remaining five white points. Finally, the colour differences between the measured and adapted colour values for each white point were calculated to evaluate the performance of each chromatic adaptation transform. The results of calculated colour differences showed small colour differences (values below 3) for a large number of colour patches for all white point pairs; in consequence, it was confirmed that it is possible to satisfactory predict the appearance of colour on a display using chromatic adaptation transforms. The best results were obtained with the XYZ Scaling model, the von Kries model also gave good results, whereas the bradford model gave contrary to expectations the worst results. It was also confirmed that the values of colour differences increase relative to the rise of colour differences between the source and destination white point, as the biggest colour difference was observed between 6500 K and 9300 K white points and the smallest between 6500 K and 7000 K. The research also showed that different chromatic adaptation transforms adapt the colour values of different colours well in respect to their lightness, chroma and hue.

The aim of this study was to compare the back length distances (BacLen) from contemporary construction systems with the measured back length distances of the Slovenian young female population to establish which back length presented in different contemporary construction systems fits best to the body dimension of a specific target market group. 160 female students (aged between 19 and 27 years) from the University of Ljubljana (Slovenia) volunteered for the study. The results showed that the measured back length distances differed significantly from those obtained from the tables of contemporary construction systems or calculated as a secondary measure according to these systems. The measured BacLen distances were the same in all size groups and did not increase as did with all analyzed contemporary construction systems. The range of measured BacLen distances inside each size group was substantial (33−43 cm) and the measured BacLen distances were not in correlation with the body height, bust girth and in consequence nor with the calculated BacLen distances. In conclusion, the values for back length distances as proposed by different contemporary construction systems differ significantly from the measured ones in the young Slovenian female population. We thus suggest including back length distance as a directly measured parameter for a pattern block construction when producing made-to-measure clothes.

People with increased secretion of sweat constantly deal with the problem of sweating already at low physical strain in various environmental conditions and seek solutions to achieve the desired thermal comfort of garments. Appropriate thermal comfort when wearing clothes can be achieved only with a suitable choice of textiles, an appropriate clothing design and the construction of clothing cutting patterns constituting the garment. This research hence focuses on the influence of fibre composition of knitted clothes and the design of men’s sports T-shirts on the thermal physiological comfort of clothes during the process of wearing in terms of thermal and sorption properties. Important parameters to determine thermal comfort are the amount of secreted sweat and the amount of sweat absorbed by clothes. The amount of secreted sweat is influenced by climatic conditions, physical activity of a person and their tendency to perspiration, whereas the amount of sweat absorbed by clothes is influenced by the thermal and sorption properties of knitted clothes, as well as by the openness of clothing. The latter enables ventilation, resulting in a more efficient heat exchange between the body and environment. For the purpose of this research, we tested the following knitted clothes parameters: thermal conductivity (l), air permeability (Q), water vapour permeability (WVP) and the ability to retain water (WRV). The influence of cuts of men’s T-shirts made from knitted fabrics of various fibre composition on the ventilation and comfort was tested on the basis of the amount of secreted sweat (Esw) during the process of wearing as a physiological parameter of a person and the amount of sweat accumulated in the T-shirt (Wsw) as the parameter of knitted clothes sorption properties. The results showed that the fibre composition of knitted clothes and the design of a sports T-shirt substantially influence the amount of sweat accumulated in the T-shirt and in consequence, the comfort during the process of wearing.

Working in hot environments usually includes the presence of several different negative influences from the environment from which it is necessary to protect the human being; therefore, it is necessary that the personal protective equipment is carefully planned. In addition to the protective functions, the possibility of cooling a person at the microenvironment level of personal protective equipment must be considered. It is important to know the options and concepts of cooling in a hot environment to prevent overheating and to increase operational efficiency in prescribed time. There are different systems for cooling down; they differ in their performance over time and in their functionality. This article deals with the passive system for cooling down which was implemented in a manufactured shirt. The passive system in a form of a non-woven fleece material, was distributed across the surface of a T-shirt on the upper chest and back parts. Non-woven fleece with hydrocrystalls in contact with cold water swells and in that state cools down a person or keeps their skin temperature at normal levels. The lower part of the shirt was made of a polyester air-netted material. Thus, we tested a T-shirt with 16 test subjects during intense training on a ski-simulator. We were interested in the cooling performance and functionality of the product. To the end, the temperature was measured using a thermal camera, while the functionality was evaluated with a subjective evaluation. The results showed differences in temperature before and after the exercise, which confirms the cooling effect. The results obtained by the subjective evaluation led us further to the optimization of the product from the perspective of a different distribution of fleece material for cooling down over the surface of T-shirts. However, the cooling mechanisms required for a short period of time are substantially different than those used in cooling at longer-lasting activities.
